Is this multiplying or what??? Anyways try calculating those numbers so basically you need to calculate 28x2 or if you have to divide them or multiply them you would get the answer is very simple
Answer:
9
Step-by-step explanation:
For this problem, you would use the GCF
Find the GCF of 45, 81, 63
GCF(45, 81, 63) = 9
45 = 9 * 5
81 = 9 *9
63= 9 * 7
Since 5, 9, 7 have no common factors, the GCF has to be 9.
This means that the greatest number of plants he can put in each row is 9.
The number of rows he uses for each plant will (obviously) vary.
The answer is A. Working the formula backwards you get that r^2=256, so r=16
It is 18-6 out of all the other ones
I'm pretty sure the answer is 1 1/16
